An Asian elephant named Koshik can imitate human speech, speaking words in Korean that can be readily understood by those who know the language. The elephant accomplishes this in a most unusual way: he vocalizes with his trunk in his mouth

The elephant's vocabulary consists of exactly five words, researchers report on November 1 in Current Biology, a Cell Press publication. Those include "annyong" ("hello"), "anja" ("sit down"), "aniya" ("no"), "nuo" ("lie down"), and "choah" ("good"). Ultimately, Koshik's language skills may provide important insights into the biology and evolution of complex vocal learning, an ability that is critical for human speech and music, the researchers say.
